Dear friends of TW AUDiO,

when I decided to found TW AUDiO in 2004, I never would have thought that our products experience such an appreciation amongst users in several dozens of countries spread over five continents today. For the confidence placed in us I would like to thank you. …

TW AUDiO was born. I became we.

Every TW AUDiO loudspeaker deployed is proof of the confidence in our brand and in what we want to achieve – being   your sound.

And that’s what we stand for – every single TW AUDiO product, every single TW AUDiO employee and of course me, as its founder.

Top class with plug’n’play. Always and everywhere matched together.
And welcome everywhere, too. The PA-SYS-ONE is our proven all-round sound system on the modular principle – with two T24N tops, four B30 subwoofers and a system amp rack with patch panel and set of cables, this is the all-round, no-worries package for takeoff.

You can even transport a complete PA-SYS-ONE in the back of a van. Loading and unloading, setting up and dismantling can be done by just one person.

But to become a classic it needs more unique properties: Whether for jazz, rock or techno, soul or classical music, whether in a small club, a theatre, a church or an open-air event, as a main PA, a drum fill or a side fill, the PA-SYS-ONE just keeps on rockin’.

And if one PA-SYS-ONE isn’t enough, you can just simply add another one. Alternatively you can drive up to four T24Ns and eight B30s with one system amp rack. Or just extend the system in the infra bass range with BSX and additional amplifiers.
All these attributes make the PA-SYS-ONE a real classic.
